The AdvanceTrac
威
with RSC
威
system includes a stability control
button on the center of the
instrument panel, a stability control
off light, and a stability control light in the instrument cluster.
The stability control light and stability control off light in the instrument
cluster will illuminate temporarily during start-up as part of a normal
system self-check, or during driving if a driving situation causes the
AdvanceTrac
威
with RSC
威
system to operate. If the stability control off
light illuminates steadily, verify that the AdvanceTrac
威
with RSC
威
system
is not manually disabled by pressing the stability control button located
on the center of the instrument panel. If the stability control light
remains steadily illuminated, have the system serviced by an authorized
dealer immediately. The message center will also indicate a failure with
the AdvanceTrac
威
with RSC
威
system.
Note:
If the system cannot be turned off, refer to
MyKey™
in the
Locks
and Security
chapter for more information.
When AdvanceTrac
威
with RSC
威
performs a normal system self-check,
some drivers may notice a slight movement of the brake, and/or a
rumble, grunting, or grinding noise after startup and when driving off.
When an event occurs that activates AdvanceTrac
威
with RSC
威
, you may
experience the following:
•
A slight deceleration of the vehicle
•
The stability control light will flash.
•
A vibration in the pedal when your foot is on the brake pedal
•
If the driving condition is severe and your foot is not on the brake, the
brake pedal may move as the systems applies higher brake forces. You
may also hear a whoosh of air from under the instrument panel during
this severe condition.
•
The brake pedal may feel stiffer than usual.
Traction control system (TCS)
The TCS is a driver aid feature that helps your vehicle maintain traction
of the wheels, typically when driving on slippery and/or hilly road
surfaces, by detecting and controlling wheel spin.
Excessive wheel spin is controlled in two ways, which may work
separately or in tandem: engine traction control and brake traction
control. Engine traction control works to limit drive-wheel spin by
momentarily reducing engine power. Brake traction control works to limit
